Local storage should use a random storage key unless unique key is defined

[TriangleJuice]

Describe the bug

When two apps use the navigation menu and there's no unique storage key specified in both apps, the one app will inherit the state of the other and vice-versa. This can be troublesome if one app uses the docked the mode and the other doesn't

To Reproduce

Steps to reproduce the behavior:

1. Integrate navigation menu in app A with possibility to switch to docked mode
2. Integrate navigation menu in app B with NO possibility to switch to docked mode
3. Go to app A and activate docked mode
4. Go to app B and reload

Expected behavior

App B shouldn't inherit the local storage preferences of app B.

Localstorage is specific to a browser origin, so I don't really see how you can get this in production (on localhost it is indeed quite likely).

[TriangleJuice]

Because - if I'm right - on production local storage will not make a difference between the many subdomains.

[jsebrech]

No, subdomains are still separate origins, see https://stackoverflow.com/questions/4026479/use-localstorage-across-subdomains

I suggest that we do some research on this and then close the issue if you're right. Thanks for starting the conversation :-)
